This is 1984 Blazer S10. Need less to say the stock 2.8 is WEAK!!! It is a 4x4 with a 4 speed manual tranny. Im looking for a good efficient engine. I hope I can find something with around 200plus hp that gets around 27 m/gal highway. Any suggestions?
I can think of a couple great chevy motors with these specs but as far as I know, they only work for fwd!! That GM 3.8L is sweet but only fw drive???
If your dead set against a 4.3, stuff a small block in there. I think you dreamin about the 27 mpg no matter what motor you choose, 17 will come first. Sorry if its not what you wanted to hear. ;)
and if your not dead set against the 4.3 i've got one with 16k miles that i'd take 1k, for,, pulling it out for a v8
oh yeah it's out of a 03 blazer.
3.4L engines were the replacement for the 2.8L (and 3.1L). These will be a stright swap, even using the same motor mounts. These were used in GM F-bodies. 4.3L are another obvious bolt in swap.
The 3.8L was also available in the F-body. How much work it would take for the motor mounts is anyones guess. 3.8L engines were also available in GM G-bodies (Cutlass Supreme, Monte Carlo, Regal, Grand Prix, etc.) until 1987 and 1988. Newer engines have more power. If your Blazer is 4WD, I don't know how well the engine will bolt up to the existing transmission.
if the truck had anything BUT a 4.3, the 4.3 will not fit because it has the same trans bolt pattern as a SBC.Quote:
